provement in Greenhouses and other Glazed Structures, of which the following is a specication.

In greenhouses as heretofore constructed with vertical sides of appreciable height the vsash-bars have rested upon and been su ported by a girder or bearer coming at t e intersection of the vertical sides and sash- Abars, and to this girder a cornice and gutter have usually been connected on the outside. These parts have cast an appreciable shadow on the plants within the greenhouse; and the l object of my invention is to obviate this shadow, to lighten the appearance of the structure, and to dispense with numerous parts.

In carrying. out my invention I employ sash-bars that are continuous-that is to say, each sash-bar comprises inclined and vertical portions with a curved intersection. The bars are preferably integral or unbroken from the sill of the said foundation to the ridge of the roof to a termination-plate or to the line of the top Ventilating-sashes. The glazing is also .preferably continuous along and between the bars. Each bar preferably comprises a metal part or bar and a coacting and connected wooden bar. I may employ f or this bar the forms shown in Letters Patent granted to me April 15, 1902, Nos. 697 ,746, and 697,747 or the form shown in my application for Letters Patent, Serial No. 69,373, liled July 23, 1901. The glazing is connected to the wooden part of this bar, and a part of this bar extends between and Y beyond the glazing.

In the drawings, Figure 1 is a verticalI cross-section representing slightly more than half of a greenhouse structure according to my invention. Figs.` 2 and 3 are cross-sections of forms of sash-bars adapted for my improved structure and which sash-bars are those shown and described in my aforesaid patent and application. Fig. 4 is a side elevation representin parts of the vertical and inclined parts an the intersecting part of the sash-bar and a section of the glazing. Eig. 5 is a vertical cross-section at the lower cnd of the sash-bar, showing a form of suppart of the present invention.

port of the same upon a foundation. Fig. 6 1s a vertical section through a form of foundation for a greenhouse structure to Which my sash-bar is applicable, and Fig. 7 is a side elevation representing a length of modified form of bar at the intersection and section of the glazing.

a represents the sash-bars. Each sashbar comprises inclined and vertical portions with a curved integral intersection, forming a substantially continuous bar, the inclined portion representing the top or roof of the greenhouse structure, the vertical part the side above the foundation, and the curved part the intersection continuously formed with the inclined and vertical parts.

b represents a foundation; c c', vertical posts within the greenhouse structure supported on suitable foundations and connected at the upper ends to purlins'd or to the base of the ridge-bar d. i

In Fig. 1, e e re resent Ventilating-sashes on opposite sides o the ridge-bar d', and f f are manuallyoperated devices for raising and lowering the Ventilating sashes e e', which are of usual construction. These manually-operated devices f f are also well known and of usual construction and are simply illustrated for the purpose of sh'owinr the complete structure and form no essentia part of `my present invention.

The foundations b t may be of concrete, brick, or other suitable material, and they may rise to any convenient or suitable distance from the ground and pass into the ground any convenient orsuitable distance, as the character of the foundation forms no 6 a subfoundation g is shown, into W lich are secured posts 'i at intervals. These posts support and have connected to them continuous angle-iron plates c 7c', the plate k being of greater Width than the plate 7c and the plate k having a larger member at right angles to the horizontal portion7 so that between the upright portions or iianges of the said plates is received and supported the foundation l). This is a convenient form of structure, wherein lthe foundation of the greenhouse structure is carried far below the Imst-line, while in Eig. 5 b represents a foundation which may sim ly pass into and rest upon the ground near t e surface.

In Fi s. 1 and IOO ` dationb in any desired manner.

' passes through the parts, the shoe in turn being connected to the sill by a bolt 4.

In Fig. 6, m represents an auxiliary sillplate on to of the foundation b, and h a sillplate Whic is the equivalent of the sill-plate h, Fig. 1, and between which sill-plate h and the auxiliary sill-plate m there is a side ven-- tilating-sash n. These ventilating-sashes are usually low and long and are hinged to the upper sill. They are sometimes used, 'but more frequentlydispensed with, and the several figures of the illustrationy are made to how the possibilities of my improved sash- In Fig. 2, o represents a U-bar of metal; r, a wooden bar received within the metal bar and secured thereto by a screw 5, -the central portion of the wooden bar r being reduced and projecting between the glass plates s, there eing lines of putty 7 in the intersections between the Wooden and metal bars in which the glasses are, embedded. This bar, Fig. 2, is one'of the Vforms of sash-bar shown in my aforesaid patent.

In Fig. 8,0 re resents a T-bar of metal; r', a wooden bar wit a centrally-reduced part to ipass between the glass plates s and with ad- ]acent grooves for putty 7, into which the glasses are embedded. This bar is shown as provided with moisture-troughs along opposite sides, and the T-bar is let into the wooden bar from the under side and is secured thereto by screws 6. This bar, Fig. 3, is the bar shown and described in my aforesaid a lication, Serial No. 69,373. Either form ofbar is adapted for use as a continuous sash-bar for greenhouses such as shown in Fig. 1, and I do not limit In self to Which form of bar I employ, althoug heretofore I have usually employed the form shown in Fig. 2'.

-In the employment of this sash-bar for reenhouses Iprefer to stop the wooden memer of the bar at the border of the Ventilatingsash e e', Fig. 1, and to continue the metal part of the bar upto connection with the ridge-bar, and I also prefer at the founday tion-line to stop the wooden part of the bar and to continue the metal part down to a secure fasteningy with sill or with the angleiron plates which form part of the foundation. In Fig. 1 the wooden part of the sash-bar stops at the sill h, while the metal part continues on down to the angle-plates c k.

' each glass down within the sill h at the mterseotions of v the series of side ventilating-saslies usually employed and illustrated by the side ventilating-sash n, past the auxiliary sill m, down within the foundation b to the upper portion of the angle-plate k in an effort to increase' the stiffness of the structure.

In Fig. 4 I have shown the curved'intersection with the inclined and vertical parts of the sash-bar, in which structure the metal part yof the sash-bar is bent and the wooden part is advantageously cut out of a solid piece and of curved form to connect with the ends of the inclined and vertical wooden parts fitting within the metal part, the meeting edges being inclined,preferably, as shown in Fig. 4, not only for -the purpose of shedding the Water, but to facilitate a secure connection at the meeting ends of the wooden part.

The glass plates o'r glazing s of my improvement are continuous from the foundation or sill plate to the Ventilating-sash to a termination-plate or ridge-bar of the greenhouse structure, and at the curved portion these glass plates may be narrow or the entire curved portion may be made of one or more glass plates. In all cases, however, the edges are abutted, or the lower edge of fplate will be lapped over the upper edge o each adjacent plate, conforming to the usual manner of laying these glass plates.-

In my improvement a minimum of space is occupied by the structure, so that a margimum of light and sunshine is obtained within the house, and there are no arts, such as the usual gutter or cornice at tfie intersection of the vertical and inclined parts, to cast appreciable shadows and interfere with the growth of the plants.

The modification Fig. 7 is illustrated for the purpose of indicating that the intersecting portion between the vertical and inclined portions of the sash-bar may be made with a very sharp bend, or, in other words, upon a small radius, too small a radius to employ bent plates lof glass. In thisevent the glasses of the inclined and vertical portions are connected by a narrow plate of metal 9, the edges of which may be abutted against she plites of glassfat either side or the joints ap e he following may be stated as among the advantages toy be gained by the employment of this form of structure for greenhouses and IOO IIO

einem and other glazed structures: The external as well as the internal appearance of the house is enhanced and amore graceful structure produced. The collection of icicles in winter is prevented,. because there is" no gutter and .no eaves exterior of the house and intersecting a portion of the glass. There is no deca of exposed cornice members, whichis IIO usua in greenhouses of ordinary character, as these parts are absent. f There is no structure which makes it possible for water to collect and freeze under the last glass and by `the expansion produced by freezing crack the glass. There is no structure that permits sliding snow to back-up, collect, cover the glass, and interfere withthe, entrance of the sunlight, nor is it possible for snow to collect, so as to add to the weight of the structure. In the present structure the water or drip on the under surface follows the glass all the l,way down to the sill and simply flows away, while heretofore at the angle produced between the inclined and vertical portions the `water or drip would spatter away from the structure back onto the plants and would cause injury thereto. With this structure, furthermore, side drafts of cold airareprevented.

Ventilating-sashes in one or more series along and at eitheror both sides of the ridgebar of a greenhouse are usually em loyed, but are frequently wholly dispense with, and therefore I do not herein limit myself to.

the employment of any ventilating-sashes in the roof portion of the glazed structure. By the use of the Word intersection greenhouse or other lherein employed I mean the curved portion `of the metal sind wooden parts ofthe sashbar (shown in Figsll', 4, and 7) that int'ervenes or cornes between, and which partis substantially integral with the vertical sides and inclined top I claim as my invention- 1. In a greenhouse or similar glazed-structure, a series of sash-bars substantiallycontinuous and extending unbroken from the foundation to a point adjacent Ato the ridge.-

bar, and each comprising a bent form of tion-plate, and each comprising' a bent form ofmetal bar for strength and a part connected thereto and to which the glasses are in= turn connected, said bars each including the short 'vertical side, the ,inclined top and curved intersection, and with plates of glass contacting at-the meeting edges and extending between the sash-bars and continuous for the length of said complete bars.

3. In a reenhouse or similar glazed structure, a serles of sash-bars substantiallycontinuous and extending unbroken from the foundation approximately .to the center ridge-bar -and each comprisinga form of metal of bent cross-section forfstren th, and a wooden bar coacting and lying para lel with and connected to the metal bar and constructed to receive the plates or lights of glass, and each of which sash-bars includes the short vertical side, the long inclined top part and curved intersection.

4. In a eenhouse or similar glazed structure, a series of sash-bars substantially continuous extending unbroken from the foundation ap roximately to the center ridge-bar land eac comprising a form of metal of `U shape in cross-section for strength, and a wooden bar received in and coacting with the metal bar lyin `parallel with andconnected to the metal har and having a projecting rib of narrower width with side shoulders to receive putty as seatsy for the plates or lights of lass, and each of which sash-bars Aincludes t e short verticalside, the long inclined top part and curved intersection.

5. In a greenhouse or other glazed structure,`a series of sash-bars substantially continuous and each comprising the short vertical sides, .the inclined topand curved. intersection, and each bar consisting of a metal part for strength and a wooden part parallel and continuous,the woodenV art at one end stopping at the sill and .at t e other end at the ventilating-sashes near the top, and the metal bar continuing at the top to a connection with the ridge-bar and at the other and lower end to connection with `the foundation.

6. In a greenhouse or similar glazed structure, a serles of sash-bars each comprising a short 4vertical side,` an inclined top and cur-ved intersection, and composed at the curved Vintersection and adjacent portions ofI an inner or under part of metal and an outer part of wood.

. 7. In a greenhouse or'similar glazed structure, a series of sash-bars substantially continuous and extending from the foundation toa point adjacent to the ridge-bar andeach comprising a bent form of metal for strength and a part connected thereto and to which the glasses are in turn connected, said barsv each including the short vertical side, the inclined top and curved intersection, and plates of glass between the sash-bars from end to end forming a continuous surface of glass.
